“…Nodularin is a relatively stable molecule, with a low abiotic breakdown rate (Twist and Codd, 1997), but much of the added nodularin could still have been degraded by the bacterial community in the sediment (MazurMarzec et al, 2009). Torunska et al (2008) report complete degradation of nodularin in three weeks when nodularin was added as extracts from N. spumigena to sediment. In contrast to this, Mazur-Marzec et al (2007) found nodularin concentrations of 2.3 ng g À1 DW in surface sediments from 20 m depth several months after a bloom and concentrations of up to 342 ng g À1 DW sediment during the bloom.…”

“…The highest concentrations were measured in the uppermost sediment layers collected during the N. spumigena bloom. Sediments with a fine-grained structure tend to accumulate a greater amount of the toxins (Toruńska et al 2008). LC-MS/MS analyses showed that, apart from NOD, demethylated analogues of nodularin ([DMAdda 3 ]NOD and [dhb 5 ]NOD) , and microcystin-LR (Kankaanpää et al 2009) were present in sediments.…”

“…Nodularin is reportedly capable of persisting for “several months” in sediments [12], and the related cyclic peptide toxins, the microcystins, have been recovered from lake sediments at a depth of 30cm, which implies a capacity for longevity in some circumstances [55]. Experimental work has shown that nodularin can adsorb to sediment particles [56]. …”
